STOCK-INDICATOR.

SPECIFICATION forming part of Letters Patent No'. 358,896, dated March 8, 1887.

Application filed February 2, 1885. Renewed January 26, 1887. Serial No. 225,580. (No model.)

To @ZZ whom it may concern:

Be It known that I, A. BUTTLEs SMITH, a

citizen of the United States, residing in the city, county, and State of New York, have invented a new and useful Stock-Indicator, of

vwhich the following is a specification.

My invention relates to certain improvements in the stock-indicator patented to me July 8, 1884, No. 301, 763, whereby the results sought to be accomplished by said patented indicator are rendered more satisfactory, as will be hereinafter shown.

In the accompanying drawings, Figure l is a front View of a stock-indicator with my invention, the upper covering of it being shown in section in order to exhibit the inclosed parts. Fig. 2 is a side view of inner mechanism of the same, the housing thereof being sectioned. Fig. 3 is an inverted plan view of the controlling-magnets and a portion of the clockwork mechanism employedin connection therewith. Fig. at is a top view of the reversing mechanism and a portion of the escape mechanism as seen above the housing. Fig. 5 is a detail view of the two magnets and their immediate or direct connections with the clock and reversing mechanisms7 a portionof the mechanism being sectioned. Fig. (5 is a detail view, partly in section, of the escape mechanism. Fig. 7 is a horizontal section in the line :c 00 of Fig. l, and Fig. 8 is a detail View of a modied construction of the escapeinent shown in Fig. 6.

In the drawings, A represents a suitable inclosure or housing of the magnets and clock mechanism; B, a clock mechanism 5 C, an escape-magnet; D, a reversing-magnet; E, a reversing mechanism, and F an exhibit device.

The clock mechanism B, which is to be wound up in the ordinary manner, is of usual construction, and consists of a drum-wheel, b, cord b', weight b2, and an ordinary train, one wheel, b3, of which latter is coupled with an escape-wheel, b4, having eight (8) steps, b, and a stopping-pin, bc. An armature-lever, c, carrying the armature c of the escape-magnet O, is pressed by means of an ordinary tensionspring, c7, against the periphery'of the escapewheel b, and thus engages with the steps b5 in the manner and under certain conditions as will be hereinafter described. An auxiliary curved hook-pawl, c2, is pivoted at c3 to the armaturelever c and pressed by a spring, o4, upon a guideplate, ci", on the pawl-stand c6, the hooked'end of which pawl c2 is moved in range with the pin b of the escape-wheel when the armature lever c is attracted by its niagnet, thereby moving the bulged portion c8 of the pawl c2 upon the guide-plate c5 and elevating the pawl. The pin b6 is so placed upon the escape-wheel b* and with respect to the pawl c2 that when the escape-wheel is stopped by the said parts the fractional portion of the exhibit device F displays zero instead of one of the fractions, as will be seen.

The wheels b3 b4 are fastened to a shaft, d, to which a sleeve, d', is loosely Iitted. The sleeve d has two bevel-wheels, c c', fastened to it, which alternately gear into a horizontal bevel-wheel, e3, according to the position of the sleeve. The position of the sleeve d is regulated by a forked head, d3, of an armaturelever, cF, tt-ed in a groove, di, of the sleeve. As the magnet D is charged, and attracts the armature d5 of the lever d* the sleeve d is drawn along, and the wheel e engages with the wheel e3, and as the magnet is released a spring, d, moves the lever d and sleeve d back to their former places, and the wheel e is thus caused to engage with the wheel c3. The stroke of the sleeve d' is adjusted by means of a set-scrcw, dl, in one of the stands a, supporting the shaft d, and the sleeve d is, by means of a longitudinal key, d8, caused to revolve with the shaft d and wheel b3 of the clocktrain.

To the hub e4 of the wheel e3 a drum, f, of the exhibit device F is fastened and revolves with it. This drumf has 0 and the fractions it, 1l, t, il, J2, -l-,rmarked upon its cylindrical surface, so that 0 is in exhibiting position when the pin D6 ofthe escapeewheel b4 is arrested by the pawl c?, as aforesaid. The wheel e3 and drum j are loosely fitted to an upright pin, f',

which is inserted into the bearing-stand c5 of the wheel e, and there fastened by a transverse pin, e6. Above the drumf a drum, f2, having the numbers l, 2, 3, 4, 5, 6, 7, S, 9, O on its cylindrical surface, is loosely fitted on the pinf, and above the drum f 2 a drum, f3, having the numbers l, 2, 3, 4, 5, 6, 7, 8, 9 and a blank space on its cylindrical surface, is loosely fitted upon the said pin f. The drum f2 is operated by the drumf, and the drumf3 is operated by the drum f2 in the same manner and by the same means as described in my aforesaid patent, the drum f2 exhibiting the units, and the drum f3 exhibiting the tens. These drums are surrounded by a slotted casing, ft, of opaque material, which maybe provided with a coating of paint without luster to avoid dazzling the eye of the observer, and a strip of straight fiat glass, f5, 0f proper width is suitably inserted into the casing ft, in order to exhibit the numbers on the drums in vertical rows. W'ith this arrangement the observer is enabled to distinctly and speedily read off the exhibited numbers ofthe respective drums, even if only allowed a side glance at the same, and no disadvantage arising from a cylindrical glass case will be experienced.

The conductingwires of the magnets C and D are connected with two separate ordinary switches placed between them and two ordinary electrical batteries. Other connectingwires are used to connect the said magnets with corresponding magnets of other stock-indicators in the same manner as described in my aforesaid patent, so that a number of stockindicators at different places are operated simultaneously by means of the said ordinary switches.

rIhe operation of my stock-indicator herein described is greatly simplified as compared with my formerpatented invention, inasmuch as one quick motion of the escape-armature is only necessary to change the exhibit oneeighth, more or less, while one prolonged charge ofthe escape-magnet will cause all the stock-indicators to show 0 on the drum f. This latter movement is always resorted to when there is a suspicion of some failure in the operation of one or more indicators of a whole line of indicators while the quotations are going on. XVhen a quotation-number is to be changed upward, the operator quickly moves the escape switch forward and back, and thereby effects a change or rise of one-eighth on the drums f of a circuit ot' indicators, or along the whole line. If the change of quotation is one-fourth, he makes another back-and! forward `motion in addition to the first, and the drums fwill exhibit a difference or rise of one-fourth, and so on. If the quotation is a fall of one-eighth, the operator moves the reversing-switch forward and holds it in that position while he operates the escape-switch in the manner above described, and the result is a fall in the value of the exhibited numbers on the drums f, as will be seen. l

The steps b5 of the wheel b constantly bear upon the armature-lever c by means of the operating-weight b2, as long as the magnet C is not charged. The abovedescribed quick @sacos movement of the escape-switch charges the magnet C for a moment, and the lever c is caused to make a momentary oscillation from and toward the escape-wheel b", thereby releasing the engaged step b5 and allowing the escape-wheel to revolve before the returning armature-lever c can rearrest the same step b5, so that the wheel moves on until the next step b5 is stopped by the returning armature-lever c.

-When a failure of operation along the line is suspected or discovered, the operator charges the magnet C by means ofthe escapeswitch, and keeps it charged,whereby all the escape-wheels along the lineare caused to revolve without stopping at any of the steps b5 until the pins b come in contact with the pawls c2 and are thus stopped. Then he releases the escape-magnet C, whereupon the armature-lever c is moved against the wheel b* and caused to arrest the next arriving step b5 of the escape-wheel- The drumsf now all along the line exhibit 0, or zero. The operator now proceeds again to telegraph the quotations in the above-described manner.

Instead of operating the drum-wheel by a weight, b2, it might be operated by an ordinary clock-spring without departing from the princi ple ofmy invention.

The modification represented by Fig. 8 relates to the escape motion, and shows the es cape-wheel G fastened to the hub e4 of the wheel e3, and, as this wheel has a forward-andbackward motion, straight notches g are provided, into which the armature-lever c enters and stops the wheel. The pin D6 is placed on the wheel G, so that when coming in contact with a lug, g, on the armature-lever c the wheelG is stopped and the drum f exhibits zero. This lug g is in the path of the pin]c6 only when the escape-magnet C is charged and the armaturelever c is removed from the wheel G, as shown by dotted lincs.

As indicating the prior state of the art, reference is here made to Letters Patent numbered, respectively, 154,309, 250,490, 267,437, and 301,763, and I would state that I claim under this patent nothing embraced by said patents.
